Voice Quality Changes in Words with Stød

Gert Foget Hansen

Stød is a prosodic feature occurring in Danish. The most conspicuous acoustic trait of stød in its prototypical form is a short stretch of irregular vocal fold vibrations, i.e. creak. However, creak is neither necessary nor sufficient to characterize stød: The occurrence of creak is not limited to syllables with stød and distinct and clear realizations of stød need not exhibit creak. To account for the inconsistent occurrence of irregular vocal fold vibrations in stød it is hypothesized that stød could be explained as a relative and dynamic voice quality movement in the form of a brief change from less to more compressed voice, potentially but not necessarily involving creaky voice. To test the hypothesis changes in voice quality are traced over the cause of comparable syllables with and without stød using a set of voice quality related acoustic measures. The results demonstrate that the timing of the peak level of compression need not coincide with the occurrence of irregular vibrations. As a consequence of these findings the proposed stød hypothesis is rejected. Moreover, the results challenge the underlying models of voice quality, as results do not conform to generally accepted assumptions about the relation between creaky voice and compression.
